One of the year’s most anticipated album/tour campaigns has been pushed back indefinitely due to the shocking announcement from the Beastie Boys camp this morning that the one of their members has been diagnosed with a cancerous tumor.

“Adam 'MCA' Yauch of Beastie Boys was diagnosed last week as having a cancerous tumor in his left parotid [salivary] gland,” reads the official press release from EMI Music. “Luckily it was caught early and is localized in one area, and as such is considered very treatable. It will however require surgery and several weeks of additional treatment. Fortunately the cancer is not in a location that will affect Yauch's vocal chords. Beastie Boys have canceled all upcoming concert appearances to allow time for Yauch's surgery and recovery. The release of the band's forthcoming album 'Hot Sauce Committee Part 1' will also be pushed back.”

This scraps dates slated for summer festivals such as Chicago’s Lollapalooza and San Francisco’s Outside Lands. Locally, this means that the band’s debut at the Hollywood Bowl scheduled for Sept. 24 will have to wait for another summer.

Yauch originally made the announcement via YouTube, where he did his best to maintain a sense of humor about the diagnosis: “It's a pain in the neck (sorry had to say it) because I was really looking forward to playing these shows, but the doctors have made it clear that this is not the kind of thing that can be put aside to deal with later."
